But I wonder if it could be 60hz humm from a ground loop. If it happens the second you plug it in tha could be. Is everything plugged into the same power strip?

Yes, everything is plugged into the same power strip. I've tried plugging it into another outlet and even plugged it into another room and still makes the humming sound.

It is probably a bad power supply circuit in the subwoofer.

Get a recommendation for a qualified local audio technician from
a local audio dealer, and let him troubleshoot it.
